Latest invisibility cloak tech can hide a single skin cell

But could lead to a real invisibility cloak

Researchers at the University of Texas in Austin have invented new a invisibility cloak technology that could eventually lead to practical applications.

A "real" invisibility cloak - insofar as the concept is understood in popular culture - would ostensibly allow a wearer to sneak around Hogwarts and other, more mundane locales without being spotted.

Of course, Harry Potter's invisibility cloak won't be much use when the zombie apocalypse arrives, since as everybody knows, zombies hunt mainly by smell.

Is that enough obligatory pop culture references? Good. Back to the news at hand, then.

Hide your kids, hide your skin cells

The ideal invisibility cloak is not just an invisible garment, but rather one that also hides whatever is underneath it.

Unfortunately, this latest invisibility cloak technology, described in IOP Science's New Journal of Physics, doesn't live up to our unjustifiably high standards - not yet, at least.

It is reportedly the thinnest invisibility cloak technology developed to date, measuring in at just 15mm thick, and it uses practical materials such as copper and polycarbonate.

The copper is patterned such that scattered light from the cloak and the object underneath it is "cancelled out," according to Slashgear.

Unfortunately, that makes it better at hiding objects from microwaves - like what's used by radar - than visible light. In its current state it can make objects about the size of one or two skin cells invisible to light, but nothing larger than that.

Promises

The project's co-author, Andrea Alu, did reportedly say that "this concept could put us closer to a practical realization," though.

Of course, she would say that - we'll be more inclined to believe it when we can slip it over our shoulders and sneak out of work early without anyone noticing. Forgive us for being skeptical, but we've heard this one before.
